Talk about hands

Manual automatic integration and stepless speed change are two concepts. Manual-automatic integration refers to an automatic gearbox with manual shift function. Continuously variable transmission means that there are few traditional fixed transmission ratios in the gearbox, and the transmission ratio can be changed at will within a certain range. Commonly known as CVT There is also an automatic CVT gearbox, which can control the fixed transmission ratio set by several programs (the automatic mode does not need a fixed transmission ratio and can be changed at any time, which saves fuel and has no sense of shifting, but it is not fun to drive). The automatic manual transmission can be CVT, traditional AT, DSG or AMT, as long as it is an automatic transmission with manual shifting, and the specific structure is not limited. As CVT said above, it has no sense of shifting, is extremely smooth and super fuel-efficient, but it is lazy at the initial stage of power, with high failure rate and no strong driving pleasure. The traditional AT has no shortcomings except high fuel consumption and poor transmission efficiency, and it is very mature. DSG, dual-clutch automatic gearbox, has high traditional efficiency and extremely fast gear shifting. AMT, automatic shift manual gearbox, if not the minimum displacement car, such as QQ, SMART. Or a car that pursues extreme sports performance, such as Ferrari.
